If you love The Hunchback Of Notre Dame, then I suggest you stay AWAY from the sequel. Seriously, it's one of the worst direct-to-video sequels they did.
Brother Bear 2 ain't too bad both in animation and story. Nice songs imo but not Phil Collins.
Mushu REALLY annoys me in Mulan 2 (and there's no Eddie Murphy) but I suppose it's not all that bad.
Pocahontas 2 has quite a few good jokes, but again, the animation isn't at it's best and if you're someone who complains about historical accuracies really don't watch.
